Prosecutors asked today that Mareo Nutall, 32, have his bond raised from $150,000 after they announced a charge of aggravated DUI involving a fatality, but Cook County Criminal Court Judge Donald Panarese Jr. declined to increase Nutal's bail.

Nutall had a blood-alcohol content of .166 percent when he slammed into the back of a disabled minivan as the van's driver, Verlinda Perry-Hill, 52, was on the phone with her daughter arranging for a tow. The minivan was stopped and had its hazard lights on when the crash happened about 10:45 p.m. on March 30, near 47th Street on Lake Shore Drive.

Perry-Hill, of the 1400 block of East 69th Street, was taken in critical condition to Northwestern Memorial Hospital and was pronounced dead there at 12:09 p.m. April 3. Nutall was taken to Northwestern and his condition was stabilized. There were no passengers in either vehicle.

Prosecutors argued that at the time of the crash, Nutall should not have been driving at all because he has a pending misdemeanor DUI case. Nutall, of the 3500 block of West Arthington Street, s scheduled for a hearing in the misdemeanor case Thursday in Cook County Traffic Court at the Daley Center.

Originally, Nutall was charged with aggravated DUI, driving on a suspended license and failure to reduce speed.
